giclee prints

In my quest to find out what print shops need to reproduce high quality enlargements from cd's I came across something called a giclee print using an iris process. Has anyone seen one? I'm attaching an url that gives some information that they want for a transfer.http://www.gicleeprint.net/DigFiles.shtml
Also I think I erred on on earlier post when I mentioned that the local print shop wanted the cmyk mode. I think they must have said rgb and that they convert to the cmyk.
